TV IMAGE PROBLEMS - When we turned the TV on the colour was distorted. Any ideas how to fix?

Question

Hi
When we turned the TV on the colour was distorted. The dvd screen shows a large circle of one colour surrounded by other rings of colour. The channels themselves have very weak colour - again with the circular effect.
We haven't moved the tv or any electrical appliances and haven't had any magnetic equipment near it.
Has anyone got any ideas how to fix this????
Thank you

Answer 3

The Demagnetizer partly engaged.....that Bullseye pattern appears when that happens.....

If it isn't broken, the next time you turn it on in the morning, it should be gone....if not, then your Thermistor is bad, or has bad solder connections, or the RELAY's contactors are frozen together......

Unplug the demagnetizer, if the bullseye disappears you have a STUCK relay......
Bad solder connections and a Bad Thermistor are Visually OBVIOUS.....

What's the Demagnetizer look like?

Well, FIRST it's attached AROUND the picture tube and generally looks like it is wrapped in electrical tape....it has two wires going to the mains area with a plug on the end, that's where you unplug it....

The relay and the thermistor and the bad connections are located REAL CLOSE to where it plugs into the board, You should see some Rectangular boxes OR the Thermistor may look like a silvery or Reddish Disc.....

You can TAP the relay gently with the plastic end of a screwdriver, which will RELEASE the contactors, but since they arced together.....they will continue to re-Arc together. So replace it if it is Stuck.....

It would have helped to know what kind of TV, but if the TV was not dropped, then it sounds like the thermistor is bad in the degaussing circuit. Sometimes they get unplugged if someone was in there. The circuit goes to a ring that is around the picture tube that eliminates magnetism from building up on the picture tube.

Answer 5

Most televisions will allow you to reset your settings. Do that first, and then begin with the color. Gradually decrease the color so your picture won't be too dark. You might want to darken the brightness a little bit. Just doing that should take care of the tint. But if not, just decrease that as well until you find a picture you like. Increasing any of those settings from the starting position will only make your problem worst.

Adam B A long answer from Reggieman but a comprehensive and factual one !!
On the other hand your shorter answer only displays your lack of knowledge on TV sets ! Cheers Pete

Answer 7

Check the cable connections, but I doubt that's the problem.

I don't know what kind of TV it is or how old. But in any case you'll have to either replace it or have it repaired by a professional (if it can even be repaired). There is no quick and easy way to fix this.

Answer 8

god i hate peple who give H U G E answers ^. anyway it sound slike your electron gun inyour CR tube is about to go - this happened with me and i also got stripes and everything over the page. however, it could also be the chip inside the tv which can be repaired for about £50 or $100. if its the CRT then its cheaper to get a new TV.

i reccommend phoning some repair guy to tell you exactly what the problem is.

Answer 9

Sounds like the CRT tube is about to go. It's warning you.

If you have a RPTV, then the convergence is way off or a light gun is about to die.

I can't think of any reason an LCD or Plasma would do this.

Answer 10

you need a new
